Πίνακας περιεχομένων:
- There carried out a study of regularities of deformation and fracture of the composite with structure-unstable binder, the peculiarities of inelastic behavior of the matrix having structural phase transformation. It was shown that there was formed the ultra-fine structure with typical size of crystallites less 10 nm having high plasticity and high capacity to hardening. This structural state of the matrix lead to the effective transmission of external loading to hardener and a dislocation slides even in typical brittle particles, for example, titanium carbide on a microlevel and rotation of the carbide particles on a mesolevel result in multiple cracking of a plastically deformed particles and, finally, to the high value of the fracture toughness. The material fragmentation on the fracture surface was founded, and the presence of transformation leads to the amorphisation of the fracture surface.
